I have a C250 2018 cabriolet AMG line and I wanted to ask on what I can do to make my car louder? Some people told me to open up my mufflers, but would it make it significantly louder or barely any louder? And would I need to remove the mufflers or is there a possibility to just open the valves as I am still new to this whole thing.

You question would likely be better answered in the W205 models forum.

If you want the OEM solution, you can find a shop to retrofit the "AMG Performance Exhaust System" which has flaps inside the tailpipes that can be open and closed through the exhaust button or driving mode.
